The BT Tv App displays the a regional Freeview channel schedules plus the BT TV IPTv channels.
In the settings of the BT TV App you should see the region the app is displaying .
If the Youview box is not receiving all the Freeview channels from your local transmitter then some channels listed in the Full TV Listings of the BT TV App will not appear in the Youview EPG.
As the channels you have mentioned are Freeview channels you may find that a retune of the Youview box may bring them into the Youview EPG if you have a suitable aerial and signal from the Freeview transmitter.
